The failure to communicate here may be due to one person speaking the language of the heart, while the other refuses to come down from his icy intellectual mountain to listen.
The faith-based thinker and the critical thinker use different methods to determine what is true about the world. All I have to offer him is reasoned, evidence argument, which is not his currency for belief, and all he can offer the critical thinker are unfalsifiable claims, which have no persuasive power the critical thinker.
Listen to what? People's unfalsifiable beliefs about gods or afterlives? Why?
As for "speaking the language of the heart," that's a euphemism for expressing thoughts that arise from outside the cortical centers that allow us to reason using language and rules of inference. It's where hunches and gut feelings and hopes and dreams live. None of those is appropriate for determining what is true about the world, just what is true about ourselves. They are necessary and valuable experiences, an important species of conscious content for determining what makes us happy, but not for deciding how the world outside of our bodies and brains works. We need analytical neocortex for that.
And of course, your de rigueur, gratuitous demeaning of rigorous thinkers. Tell the thread how offended you are to have your special way of knowing rejected by critical thinkers without using those words.
One can state a fact that is unknown and has never been proven.
I wouldn't call that a fact. For me, facts are demonstrably correct statements, meaning that they accurately map some aspect of our reality. Did you mean something that was would later be shown to be a fact?
The burden of proof rests upon the one who seeks.
The burden of proof arises when one wants one's claim to be believed and is dealing with a critical thinker capable of recognizing a sound argument and willing to be convinced by one. Absent either of those, there is no burden to support any claim.
If God exists then God can be found. God can be found. On the other hand, how many really seek God?
I seek to understand the world and myself, not gods. Why would one seek for a god? And how? Praying? Reading holy books? Some believers tell me that they sense a god directly, but I don't accept their interpretation of what they are experiencing, nor that they can sense a god not apparent to all who have the same detection apparatus.
